Alexander was not really an innovator. He followed previous grammarians in condemning elision, and in what he says of quantity and accent. In his syntax he endeavoured to set forth rules conforming to the best Latin usage of his time, like other mediaeval grammarians before him. He was indeed vehement in his advocacy of recent and Christian authors as standards of writing, and he inveighed against the scholars of Orleans, who read the Classics, and would have us sacrifice to the gods and observe the indecent festivals of Faunus and Jove.[186] But others defended the Orleans school, and perhaps still regarded the Classics as the best arbiters of grammar and eloquence. There exist thirteenth-century grammars which follow Priscian more closely than Alexander does.[187] Yet his work represents the dominant tendencies of his time. Twelfth and thirteenth century grammarians recommended to their pupils a variety of reading, in which mediaeval and early Christian compositions held as large a place as Virgil and Ovid. The _Doctrinale_ advocates no work more emphatically than Petrus Riga’s _Aurora_, a versified paraphrase of Scripture. Its author was a chorister in Rheims, and died in 1209.[188] The works of scholastic philosophers were not cited as frequently as the compositions of verse-writers; yet mediaeval grammarians were influenced by the language of philosophy, and drew from its training principles which they applied to their own science. Grammar could not help becoming dialectical when the intellectual world was turning to logic and metaphysics. Commencing in the twelfth century, overmasteringly in the thirteenth, logic penetrated grammar and compelled an application of its principles. Often grammarians might better have looked to linguistic usage than to dialectic; yet if grammar was to become a rational science, it had to systematize itself through principles of logic, and make use of dialectic in its endeavour to state a reason for its rules. Those who applied logic to grammar at least endeavoured to distinguish between the two, not always fruitfully. But a real difference could not fail to assert itself inasmuch as logic was in truth of universal application, while mediaeval grammar never ceased to be the grammar of the Latin language. Nevertheless its terminology was largely drawn from logic.[189]
